TO ALL WHOMIT 'MAY CONGERN: Y

Be it known that I, EDWIN B. BUTLER, of` NewBritain, county of Hartford, and State of Connecticut,l have invented certain new and useful Improvements in the Manufacture of Wagon-Hub Bands; -and' to enable others skilled in the art to make and us'o the same, I will proceed .to describe the mode or process of execution, by referring to the'drawings, in which the samey lettersindicate'like parts in cach of the figures.

The nature of this invention will be understood*from-the;specification and drawings.

Heretofore, wagonhub bands (as an article cf manufacturelhave been made of malleable iron, which present a good external appearance, but,owing to the'deceptive'character of the material, (and the imperfect manner of rendering them mallcable,) from which they are produced', produces, very often, impcrfectand unreliable bands, which render them insecurea'nd unreliable for use. f 'Io remedy this/want ofsecurity, .and toproduce a perfect and reliable article, equally cheap and merchantable, is'tho object ofthis invention. i

In the accompanying drawings, B is al die, in which uniformity of shape is given to the band.v C is a punchdie, which works into the forming-die, to compressthc band Ainto the shape of said die; A is the band', shown 4 as being firmly compressed, on all sides, by kpunch andjdiev C BI. The dieB, besides having the outside shape and size formation of the band Aworked therein,has'a continuation ofthe depression or orifice, of equal diameter',

vrequired for the inside diameter of the band at its lower` or smallend. I The punchor upper die C ismadetaperu ing, from a to b, so as to correspond with the taper or shape ofthe dic B, and'allow thel space or the sides of the die and punch to be parallel with each other'. The lower` end of the punch C is equal in diameter from I: to e, which fits closely and works freely in the die B, from al to e; ,'Thedie C is also provided with a shoulder, E, which fixes the downward motion, of said die. i These dies are fitted into drop or press inthe-common way.

I The iron bars, from which the bands are cut, are about the-thickness required for the band, and a little wider than what is required for the widthpf the band.l The blanks are cut from these bars the required length, so that, when welded together, they will be .nearly thediameter.required for a band. After thesebands have been weld'edtogethcr, they are heated to a proper heat, and placed, one at a time, in the die B. The die C then descends, the'lowcr end of which first passes through the band, and enters the lower portion ofthe die D, which prevents the metal from working down below thc shoulder g, thus continuing its downward motion, until the metal ring` is firmly7 compressed (to fill the dieformation) between the dies C B, and the shoulder E'of the punchdie C rests upon the upper surface of the die B. l c

Thus I am enabled to produce an improved article of manufacture, which is strong, durable, and reliable for use, rich in its appearance, and cheap of manufacture. v

I believe I have thusshown the nature, the. mode or process of manufacture, and thegreat advantage to be derived therefrom, so as to enable others skilled to make and; Ause therefrom. i

,I claim the method herein described of making .huh-bandsfgl that is vto say, takea strip of metal of width equal to that required for the band, and of proper length, welding the two ends of. said strip'together, andafterwards swaging the same in dies, l constructed substantially as set'forth.
